|x-5|=18

Lösung

∣ x - 5 ∣ = 18

x = - 13 or x = 23

Schritte zur Lösung

∣ x - 5 ∣ = 18

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 5 = - 18 or x - 5 = 18

x - 5 = - 18 or x - 5 = 18

x = - 13 or x = 23

3 - 7 ∣ r ∣ = 66

2 ∣ x + 2 ∣ = 10

7.5 \times (- ∣ 2 x ∣ - 5) = - 112.5

∣ 10 x + 5 ∣ = ∣ 5 x + 10 ∣

∣ x + 3 ∣ = 2 ∣ x - 1 ∣
